Tom O'Keefe/Patti Loken <br />March 18, 1999 <br />Page 2 <br />I.ORONO'S KEY OBJECTIVES RELATED TO THE DESIGN OF NEW HIGHWAY 12 <br />ARE AS FOLLOWS: <br />1. <br />2. <br />3. <br />4. <br />5. <br />6. <br />7. <br />Ensure the final design and operation of the County Road 6/Highway 12 interchange, <br />and of new Highway 12 in the area of this interchange, are adequate to ensure free <br />flow of trafiSc on both County Road 6 and Highway 12 well into the future. The key <br />traffic movements here are westbound new 12 using the loop to westbound County <br />Road 6, and eastbound County Road 6 traffic using the entrance ramp to eastbound <br />new Highway 12. In addition to the importance of this interchange operating <br />effectively itself, the free flow of traffic on new 12 and County Road 6 is extremely <br />important to the effective future operation of the entire east/west transportation <br />system in Orono. <br />Maintain the design of the Wayzata Boulevard/Highway 12 interchange as the one <br />that works best operationally in terms of the safe and efficient movement of traffic. <br />Assure the fi’ee flow of traffic on new Highway 12 between Wayzata Boulevard and <br />County Road 6 by providing no ingress or egress to new Highway 12 anywhere <br />along the corridor except at the County Road 6 and Wayzata Boulevard interchange <br />areas. <br />Facilitate the free flow of traffic on what will be old Highway 12 by eliminating the <br />semaphore at the intersection of Wayzata Boulevard and old Highway 12. <br />Preserve Orono Orchard Road as a local roadway serving local trips. <br />Limit lighting along the corridor to the bridge and interchange areas only, to <br />minimize spillover of light from the corridor to adjacent properties. <br />Mn/DOT is working with the City of Long Lake to determine the magnitude of <br />stormwater flows that can be diverted from the lake to a stormwater pond in the <br />location of the Long Lake sewer pond. Any diversion of stormwater must be limited <br />to an amount that will flQl cause flooding problems downstream along Long Lake <br />Creek, and will dqI result in a reduction in the quality of water running through Long <br />Lake Creek to Lake Minnetonka. <br />8. Minimize the noise impacts of the new roadway and the relocated railroad. <br />9. Coordinate the pedestrian/bike trail system being constructed along the Highway 12 <br />corridor in Long Lake with the Orono trail system.1
